This is not a very good question and you will most likely not get a good answer. What information are you trying to get from this question? If you are trying to learn how to use the Quote system in Salesforce, this is not the place for that type of question. I would recommend that you look towards the Salesforce documentation and / or Salesforce training to learn how to use the Quote system. If you are having a different issue, please expand further upon your request.
